Struct DTLSConn 

pub struct DTLSConn { /* private fields */ }

One DTLS association: the handshake state machine plus the record layer around it.

Implementations

impl DTLSConn

pub fn new( handshake_config: Arc<HandshakeConfig>, is_client: bool, initial_state: Option<State>, ) -> Self

Creates a connection in the given role, ready to handshake.

Errors

Fails if the configuration is invalid — no certificate for a server, or an unusable cipher suite list.

pub fn incoming_application_data(&mut self) -> Option<BytesMut>

Takes the next decrypted application payload, if one is ready.

pub fn outgoing_raw_packet(&mut self) -> Option<BytesMut>

Takes the next datagram the caller should send.

pub fn write(&mut self, p: &[u8]) -> Result<()>

Queues p as application data, encrypting it once the handshake has completed.

Errors

Fails if the connection is closed or the handshake has not finished.

pub fn close(&mut self)

Begins an orderly shutdown by queueing a close_notify alert.

pub fn connection_state(&self) -> &State

connection_state returns basic DTLS details about the connection. Note that this replaced the Export function of v1.

pub fn read(&mut self, buf: &[u8]) -> Result<()>

Feeds one received datagram into the connection.

Errors

Fails if the record is malformed or fails authentication.
